From The Edwin Garcia Links Machine, and this is a wonderful, well-explained video, it's Measuring the Universe. Also, and this is one of the most amazing bits of alternate reality I've ever seen: Jerry's Map. One more, and it's a corker: THE ABDUCTION OF GENERAL KREIPE ("Documentary about the reunion of Cretan and British World War II heroes -- and their abductee, General Heinrich Kreipe"). You're not done yet, and this is may be the best of all: Various Forms of Lithic Disguise. As it turns out, the Swiss have constructed the most elaborate and cleverly concealed series of landscape defenses in the history of the world.
